GONG.

Specification of Letters Patent.

Application filed. February 24-, 19 12. Seria1l\To. 679,540.

To all whom) it may concern:

Be it known that I, LOUIS A. KLING, a citizen of the United States, residing in Elizabeth, county of Union, State of New Jersey, have invented certain Improvements in Gongs, of which the following is a specification.

My invention relates to certain improvements in automatic gongs for use in street cars and other vehicles in order to sound an alarm.

The object of the invention is to so construct the gong that it will automatically ring for a given length of time; the spring being automatically wound from the brake mechanism or other operating mechanism on the'car or vehicle.

In the accompanying drawings :Figure 1, is a side View of my improved gong, the

platform of the car being in section; Fig. 2, is an enlarged sectional view on the line 2-2, Fig. 3'; Fig. 3, is a sectional plan view on the line 33, Fig. 2; Fig. 4, is a transverse sectional view on the line l4, Fig. 3; Fig. 5, is a transverse sectional view on the line 55, Fig. 3; Fig. 6, is a detached perspective view of the ratchet wheel; Fig. 7, is a detached perspective view'of the cam; Fig. 8, is a detached perspective view of a portion of theactuating spring; Flg. 9, 1s a perspective view of the plunger; Flg. '10, is a perspective view of the pivoted dog; and Fig. 11, is a sectionalview on the line 11l1, Fig. 3.

A is a platform, and secured to the under side of the platform is a frame B forming a casing B for the mechanism, and having a post I) to which the bell or gong G is secured. Mounted in the casing B is a shaft O, and loosely mounted on'this shaft is a pinion c which meshes with a segment 0 of a lever O pivoted at b to the casing B. The arm 0 of the lever O is connected to the brake mechanism of the car for the purpose fully described hereafter. On the hub of the pinion 0 is a ratchet wheel cl .wlth which engages the short arm of a pawl D pivoted at d to the casing E inclosing the spring E. The long arm of the pawl 1) 1s attached to a pin 6 on the casing through a spring d so that the casing E is free to move in the direction of its arrow, the pawl slipping past the ratchet teeth, but when the ratchet wheel is turned by means of the lever C it will turn the casing E and wind the spring. One end of the spring is attached to the outer end of the casing, while the other end is attached to a hub e keyed to the shaft so that the shaft is rotated by the action ofthe spring.

In order to prevent the breaking of the spring by overwinding, in the event of the bell not being used under normal conditions, I slot the casing E and e and secure a pin 6 on one of the coils of the spring, in the manner shown in Fig. 8, so that when the spring is wound to a certain point, the pin 6 will be drawn toward the center of rotation and will automatically press upon the long arm of the pawl D and force it out of engagement with the ratchet, so thatthe ratchet wheel is free to rotate without winding the spring beyond a certain point. 7

On the periphery of the casing E are ratchet teeth 6*- which engage the pawl'b pivoted at?) to the casing B, so that while the casing E can move in the direction of its arrow, it is prevented from moving in the opposite direction by the pawl b.

Secured to the shaft O is a gear wheel F. This gear wheel meshes with a pinion h on the shaft'H mounted in hearings in the casing 13;, and secured to the shaft H is a ratchet it having shoulders It with which engagetheends of the dog I which is pivoted at z' to the casing. This dog is held in engagement by a spring 2" and is forced out of engagement by the projection n on the plunger N mounted in the extension B of the casing, as clearly shown in Fig. 2, and this frame is forced down by the pin N, which is detachably mounted in a socket in the plunger.

Pivo-ted at m to the casing B is a lever M. The arm m of this lever rests against the ratchet and is held in contact'therewith by the coiled spring m The arm m of the lever M is so shaped as to be struck by the clapper s on its'rebound, as fully described hereafter. The striker S is pivoted at s to the casing, andthere is an arm 8 with which the plunger N comes in contact when a single stroke is given to the striker. In this event the striker is actuated directly by the plunger. This method of operating the gong may be used should the automatic mechanism become inoperative. WVhen the plunger is pushed down and held for the purpose of giving one or a series of strokes, then the clap 11o per is actuated by a lever T pivoted at t to the casing; the arm t of the said lever bearing against the back of the striker S, while the arm 25 extends over a cam K having two arms is, 72 in the present instance. This cam is secured to the shaft H, which is geared to the shaft C. A spring U is mounted between the arms 25 and the underside of the frame B, as clearly illustrated in Fig. 2, and this spring tends to force the arm 23 toward the hub K, and to force the arm 23 against the striker S.

The operation of the gong is as follows: As above described, the level 0 is attached to the brake mechanism or other moving mechanism of the car, or specially designed mechanism, so that on the actuation of the lever it will wind the spring. The overwinding 'of the spring is prevented, as above described, by the pin 6 coming in contact with the pawl -D which 1s automatically thrown out of engagement, so as to disconnect the lever and the spring easing. The pawl Z) holds the casingE against rotation which would cause the unwindlng of the spring, and consequently, in order to unwind the spring, the shaft G must rotate.

When it is wished to strike one blow on the gong independent of the ringmg device, then the foot pinN is pressed down so that the plunger will'contact with the arm 8 of the striker S, causing the clapper s to contact with the edge of the gong Gr, but if it is desired to cause the clapper to strike one or a series of blows on the gong by means of the operating device, then the pin N is forced down and held, causing the extension n of the plunger N to actuate the dogI, forcing it out of engagement with the shoulder ]L2 on the cam h and this immediately releases the shaft H, so that it will turn by the action of the spring, through the gears h and F, and, as the shaft rotates, the arm in on the hub K presses the arm 23 of the lever T against the pressure of the spring U and when the lever is released, the spring forces the arm 23 against the striker S which is driven forward, causing the clapper s to strike the blow. On the recoil of the striker the clapper contacts with the arm m of the lever M, which in the meantime had stopped the rotation of the shaft H, owing to its arm m engaging the shoulder h on the cam h and this recoil throws the arm out of engagement again and the shaft is again-set in motion, and the arm 72 again strikes the'lever T which in turn operates the striker S, causing the clapperto repeat the blows on the gong as long as the foot is pressed upon the pin N, but as soon as the foot is released from the pin, the spring 6 raises the plunger N and forces the dog I into engagement with the shoulder 72, on the cam H, stopping the rotation of the shaft and, consequently, the movement of the other parts of the mechanism. Therefore, it will be seen that by the above construction the motor-man, or other driver of the vehicle, can either strike a single blow on the gong or cause the mechanism to strike one or a series of blows at will.

The combination of a gong; a spring; means for winding the spring; a holder to prevent unwinding of the spring; a plunger actuated by the operator; a striker having an arm with which the plunger can come in direct contact to cause it to strike a blow on the gong; and mechanism coimected to the spring for causing the striker to strike one or a series of blows on the gong, said mechanism being also released by the plunger.
